我想在A面中的复合材料中放置3个固定尺寸的组。我想放置这个组的图像和标签中间。我的示例图像和代码如下。问题在于组的大小是根据标签大小调整的,标签写在组的顶部,但我希望地方组的大小相同,以覆盖A边的宽度,标签应该垂直居中。如何在SWT中设计复合材料

private void designComposite() { 

    Section sectionA = toolkit.createSection(form.getBody(), Section.TITLE_BAR); 
    sectionA.setText("A"); 

    Composite sectionClientA = toolkit.createComposite(sectionA); 
    sectionClientA.setLayout(new RowLayout()); 

    Composite dynamicDataComp = toolkit.createComposite(sectionClientA); 

    dynamicDataComp.setLayout(new RowLayout()); 

    Group group_incom = new Group(dynamicDataComp, SWT.NONE); 
    group_incom.setLayout(new RowLayout()); 
    Label lbl_img_incom = new Label(group_incom, SWT.CENTER); 
    Image img_incom = new Image(lbl_img_incom.getDisplay(), 
      "D:\\projects\\ATMGW_SW\\Code\\atmgw-client\\icons\\in_arrow.png"); 
    lbl_img_incom.setImage(img_incom); 
    group_incom.setText("# of Incoming Messages :"); 
    Label lbl_incomMsg = toolkit.createLabel(group_incom, "99", SWT.CENTER | SWT.VERTICAL); 
    Font incomFont = new Font(lbl_incomMsg.getDisplay(), new FontData("Arial", 12, SWT.BOLD)); 
    lbl_incomMsg.setFont(incomFont); 
    lbl_incomMsg.pack(); 

    Group group_outgo = new Group(dynamicDataComp, SWT.NONE); 
    group_outgo.setLayout(new RowLayout()); 
    Label lbl_img_outgo = new Label(group_outgo, SWT.CENTER); 
    Image img_outgo = new Image(lbl_img_outgo.getDisplay(), 
      "D:\\projects\\ATMGW_SW\\Code\\atmgw-client\\icons\\out_arrow.png"); 
    lbl_img_outgo.setImage(img_outgo); 
    group_outgo.setText("# of Outgoing Messages :"); 
    Label lbl_outgoMsg = toolkit.createLabel(group_outgo, "145639612", SWT.CENTER); 
    Font outgoFont = new Font(lbl_outgoMsg.getDisplay(), new FontData("Arial", 13, SWT.BOLD)); 
    lbl_outgoMsg.setFont(outgoFont); 
    lbl_outgoMsg.pack(); 

    Group group_error = new Group(dynamicDataComp, SWT.NONE); 
    group_error.setLayout(new RowLayout()); 
    Label lbl_img_error = new Label(group_error, SWT.CENTER); 
    Image img_error = new Image(lbl_img_error.getDisplay(), 
      "D:\\projects\\ATMGW_SW\\Code\\atmgw-client\\icons\\error.png"); 
    lbl_img_error.setImage(img_error); 
    group_error.setText("# of Error Messages :"); 
    Label lbl_errorMsg = toolkit.createLabel(group_error, "345", SWT.CENTER); 
    Font errorFont = new Font(lbl_errorMsg.getDisplay(), new FontData("Arial", 13, SWT.BOLD)); 
    lbl_errorMsg.setFont(errorFont); 
    lbl_errorMsg.pack(); 

    sectionA.setClient(sectionClientA); 

}

您可能想尝试[WindowBuilder Pro](http://www.eclipse。 org/windowbuilder /) – Kai

您正在泄漏图像和字体。如果您创建图像或字体,则必须安排它在不再需要时进行处理。也不要多次创建相同的字体,这是浪费内存。 –

谢谢greg-449和user714965,我再次修复了我的字体定义,WindowBuilder Pro可能很有用,但我不想使用生成的代码。我更喜欢写我自己的代码。 – selentoptas

使用GridLayout并设置列相等的宽度:

Composite dynamicDataComp = new Composite(parent, SWT.NONE); 
    dynamicDataComp.setLayout(new GridLayout(3, true)); 
    dynamicDataComp.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false, 1, 1)); 

Group group_incom = new Group(dynamicDataComp, SWT.NONE); 
     group_incom.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false, 1, 1)); 
     group_incom.setLayout(new RowLayout()); 

//...

的一种方法是使用GridLayout父复合,并告诉它使用3个相等大小的列:

Composite dynamicDataComp = toolkit.createComposite(sectionClientA); 

dynamicDataComp.setLayout(new GridLayout(3, true));

我做到了,但不起作用。我希望每个小组的大小相同,并且会覆盖A方的宽度。虽然我创建了GridLayout,但显示没有改变。 – selentoptas
